Examples o
28、f this M without restriction on the amount consumed; free-to-air; with perfect delivery quality; in any environment. The deployment opportunities addressed in clause 8 of the present document cover specific aspects of this central use case. In other words, the convergent solutions described are prim
29、arily aiming at delivering audio-visual media services to personal devices, in particular smartphones and tablets. Deployment opportunities are also not restricted to this use case as they can enable additional services (e.g. social media, non-linear broadcast services) and consumption on other devi
30、ces (e.g. large screen TV) or in complement of other devices (e.g. HbbTV). From an end-user perspective, the larger the number of use cases enabled or supported by a specific solution, the higher the attractiveness of such solution. It is also a benefit if the functionalities enabling the use cases
31、are available on a wide range of user devices. Users tend to select their devices based on multiple criteria, with the services that are enabled being just one of these criteria. Attractive devices are a prerequisite for any successful mass media service. Some of the deployment opportunities, in par
32、ticular 2, 4, 6 and 8, outlined in clause 8, while primarily aiming at mobile devices, may have a potential to serve stationary devices equally well, either now or in the future. The use cases enabled by a technology solution can be classified according to the main characteristics of the audio-visua
33、l media service delivered. These include: The type of service(s) and the time spent with different services The type of user device(s) The user context in which the service is consumed (e.g. in the home or on the move, indoors or outdoors) There are many different types of audio-visual media service
34、s, user devices and situations in which a service can be used. For the purpose of this analysis the following categories are considered to be adequate as shown in Table 5. ETSI ETSI GR MBC 001 V1.1.1 (2018-06)16 Table 5: Service categories, device categories, user environment Service categories Line
35、ar media services A linear service is the traditional way of offering radio and TV services where the content is organized in a sequence that may consist of e.g. news, shows, drama, movies, or documentaries. That sequence is distributed as a stream of programmes that reach the viewer according to a
36、pre-defined schedule. The viewer can tune in to a channel but cannot alter the schedule of programmes. Linear services are the most common way of viewing live content (e.g. sport events, concerts, news). On-demand AV services On demand audio-visual services require the user to take action beyond the
37、 simple selection of service as in the case of linear services. Typically, the user can select individual pieces of content from a library and can control at least the timing and sequence of the viewing or listening. Advanced on-demand services may offer many other options with various degrees of us
38、er engagement and interactivity. Particularly popular are time-shifted TV services (also known as TV on-demand or catch-up TV) where the content that has been broadcast as linear TV is made available in a library for on-demand viewing within a certain time window (e.g. from 7 days to up to a year su
39、bject to content rights). Other forms of on-demand media services include streaming or download of content from a library, irrespective of whether or not it has been aired on linear channels. Push Video-on-Demand (or Push VoD) is a particular form of on-demand service where content is loaded on the
40、user devices for future use. One variant is the PVR-based on-demand viewing, where the content is received as linear TV and recorded locally for future viewing. Furthermore, many additional options could be associated with the basic audio-visual content, such as second screen applications providing
41、additional content, dedicated web and cross-platform content, integration with social networks. See note. Device categories Mobile device It is assumed that mobile user devices are the main target of the 3GPP-based infrastructure. It is further assumed that, in describing individual use cases, no di
42、stinction is required between smartphones and tablets. Most mobile devices have an uplink capability. However, 3GPP included a receive-only mode in the Release 14. Stationary radio and TV set It is assumed that a radio or a TV set is connected to an external antenna or a set top box. Conventional ra
43、dio and TV sets do not have an uplink capability but connected devices do, either via an external box or integrated in the device itself. It is noted that a stationary TV set may serve as a screen whilst another device, connected to the TV set acts as an actual media player (e.g. media streaming box
44、). User environments In the home There are substantial differences between these two settings in particular in terms of typical user behaviour, reception conditions, and the availability of network infrastructure. An important difference between the two environments is the level of control over the
45、access networks. In the home it lies with the users themselves which access mechanism to choose, as property owners can decide to equip their house as they choose (Terrestrial or satellite antenna, fibre, cable or copper fixed networks). On the move users have to rely to a large extent on access opp
46、ortunities which lie beyond their control, as they cannot influence the network setup. On the move NOTE: Whilst the present analysis focuses on audio-visual media services, some aspects may also apply to the distribution of other type of data content such as traffic and weather information, emergenc
47、y services, software distribution, digital signage, and IoT. The deployment opportunities presented and discussed in clause 8 of the present document seek to enable some or all of the use cases in Table 6, in a technically and commercially sustainable way.
